ISO 2689 Flammability Testing of Fuel Tank Systems
The ISO 2689 standard addresses the flammability testing of fuel tank systems, a critical aspect in aerospace and aviation for ensuring safety and regulatory compliance. This test is essential to determine the ignitability and flame propagation characteristics of materials used in fuel tanks. The aerospace industry places an immense emphasis on fire safety, particularly given the hazardous nature of jet fuels like JP-8+100 or aviation gasoline.
The testing process involves exposing a fuel tank to specific conditions that simulate real-world scenarios where ignition might occur due to friction, lightning strikes, or other external factors. The objective is to assess whether the fuel system will self-extinguish and how it behaves under different temperature and pressure conditions.
At Eurolab, we specialize in performing ISO 2689 tests with precision and reliability. Our team of experts ensures that every test adheres strictly to international standards like ISO 2689:1975 and ASTM D4303-18. We utilize cutting-edge equipment such as the cone calorimeter, which is capable of measuring heat release rates, smoke production, and oxygen consumption during flaming combustion.
The test setup typically includes a fuel tank that is pressurized to simulate operational conditions. The fuel is then ignited, and the subsequent flame propagation is closely monitored. Our facilities are equipped with advanced instrumentation to capture detailed data on the burning characteristics of the material used in the fuel tank.
One key aspect of this testing is the evaluation of self-extinguishment properties. According to ISO 2689, a material passes the test if it extinguishes within five seconds after being removed from the flame source. This criterion ensures that any material used in aircraft fuel tanks has adequate fire resistance.
Our laboratory also provides comprehensive reporting services, offering detailed analysis of the testing results along with recommendations for improving materials and design. This data is invaluable for quality managers, compliance officers, R&D engineers, and procurement teams who need to ensure their products meet stringent safety standards.
Scope and Methodology
| Test Parameters | Description |
|---|---|
| Initial Fuel Pressure | The fuel tank is pressurized to simulate operational conditions. |
| Ignition Source | A specified flame source ignite the fuel vapor. |
| Flame Propagation | Measurements of flame propagation velocity and heat release rate. |
| Oxygen Consumption | Determine the amount of oxygen consumed during combustion. |
The methodology for ISO 2689 testing involves several critical steps. The fuel tank is first pressurized to simulate operational conditions, typically at a specified pressure level. An ignition source is then applied to the fuel vapor inside the tank. The flame propagation velocity and heat release rate are measured using advanced instrumentation such as the cone calorimeter.
The test also evaluates the oxygen consumption during combustion, which helps determine how much oxygen is consumed by the burning material. This data is crucial for understanding the fire resistance properties of the materials used in fuel tanks. The testing process adheres strictly to international standards like ISO 2689 and ASTM D4303.
At Eurolab, our team of experts ensures that every test is conducted with precision and reliability. We use state-of-the-art equipment and follow strict protocols to ensure accurate results. Our comprehensive reporting services provide detailed analysis of the testing results along with recommendations for improving materials and design.
